My invention relates to metallic box strapping, the main object'bemg toprovide an improved construction whereby sucl'r strapping may be easilynailed in place on a. box, and whereby when in place it will guard thenail head. or heads from contact with the floor, so that the box towhich the strap is applied'may be easily pushed over the floor withoutscratching or tearing, the same.

Box strapping, as ordinarily employed, is made from plain" metal stripswhich are nailed at intervals to the box. In applying such straps, it ismost desirable to drive the nail obliquely, so that as the nail isdriven in, the draft of each nail will be in a direction to tighten thestrap. In view of the smooth surface of the ordinary strap, it ispractically impossible to puncture the metal with a nail which standsobliquely when it is being driven. Consequently it is common practice tofirst puncture the metal by driving the nail through the strap with thenail placed vertically. When the puncture is made, the nail is placedobliquely,

as aforesaid, and the driving is continued. T he swinging of the nailfrom the vertical to the oblique position tends to produce someunnecessary slack in the strap, so that the drag of the nail as it isreceiving the last few blows is insuiiioient to properly tighten thestrap.

By my improvement the nail may be placed at an angle to the strappreparatory to puncturing the latter, and may be driven without dangerof slippage, every blow'on the nail being in a direction to produce adrag on the strap which will take up the slack and cause said strap'tohug tightly to the box. These and other advantages will be apparent tothe mechanic skilled in this art, from a reading of the followingspeciication. I

The strap is preferably made from sheet metal and provides a central webportion 1; which is transversely knurled or corrugated. At each edge ofthe web portion 1 there is a corrugated border 2-2, which is preferablyside'of the strap along opposite edges, as indicated in Fig. 3, so as toproduce a smooth convex bearing surface standing well above the web l. 3repre'sentsa nail, which, as shown in Fig. 2, is applied. obliquelytothe metal strap, the point of the nail being lodged in oneof theknurls of the web 1, whereby the puncturing blow may be given to thenail without danger of slippage, even though said nail is placedobliquely, When the nail is fully driven intoplace, thehead will belocated between the two corrugated borders 2-2 and will be protectedthereby from contact with the floor when the box rests thereon, so thatsaid box may be moved about without danger of tearing the floor byengagement with the nail head.

The method of producing the strap con 'struction is immaterial to. thisinvention. falthough ordinarily plain sheet stock would be employed andsubjected to pressure sufficient to produce the transversely corrugatedorknurled web andthe'raised bearings or borders at each edge thereof.

From the foregoing it is apparent thatgreat economies will be effectedin the application of the strip or strap to a box, because'the nailsmaybe started at an angle, said'nails beinginclined ina direction sothat blows against the same will be in a directionto tighten the strapon the box, thus securing at once a two-fold advantage resulting fromthe employment of the knurled or roughened web.

In the claims, for want of a better term, I may refer to the raisedborders 2-2 as elevated bearings.

What I claim is:

1. A metallic box-strap for packing cases and thelike, comprising amainbody portion, a raised bearing extending longitudinallythereof, anda roughened external sur .face portion adjacent to said raised bearingadapted to hold the point of a nail to pretentl slippage thereof,whereby. said nail may be driven at an angle relatively to the Y '2.'
